With this search interface you are able to query the international inventory of moored current meters. You may opt to use a simple or advanced query form. Both forms allow you to build a query from a number of categories, each of which is initially set to a broad default value that you can make narrower using the 'Refine' button.
It is not essential to start at the top of a form as the options available in all categories are automatically updated depending on your selections. We recommend that you start with your most important criteria. Your current search criteria are updated and displayed in the search form as you make your choices.
Please be aware that the categories that are specific to the advanced search will be reset, should you opt to switch from an advanced to a simple search.
You may, if you wish, refine any of your selections at any time. A history of your previous choices is maintained for each category.
After each update, the number of records that match your selection will be displayed at the bottom of the page. You may view the results of your search at any time.
